SWGT4 Lightweight Flywheel & Sport Clutch Kit
Product Type: Transmission
Application: Cayman GT4 & 981
With our single mass (Light Weight) flywheel kit, you get considerably better acceleration resulting from less rotational mass (especially in lower gears). Porsche does the very same thing with the manual GT3RS (2007-2012) to give it an edge over the standard GT3 models. Upgrading to a lightweight flywheel from dual-mass helps overcome the engine's feeling lethargic or lazy, and this upgrade greatly improves the overall response of the engine to throttle input.
A single-mass flywheel is a one-piece, rigid disk of metal, either aluminum or steel. Our flywheel also comes with new flywheel bolts for installation. The weight difference is significant with the stock dual-mass weighing in at 28.5 pounds vs. our single -mass piece at 14.3 pounds.
We also provide an upgraded sport clutch disk, sport pressure plate, and release bearing assembly to handle more power and torque than the original unit. As an added bonus the clutch pedal feel is actually slightly "lighter" than factory.
We have used our light weight flywheel kits over the years on our own shop R&D cars and personal cars including the 996, 997, 987 Cayman S and of course our GT4. In essence we don't feel at home in a naturally aspirated engine without our light-weight flywheel treatment!
After the car warms up and at idle there is some additional rattle/noise from the transmission. This is not very noticeable like on other cars, but it is normal and similar in principle to that found on the 997 GT3RS.
